ABSTRACT:
A closure for a cylindrically shaped ice cream carton or the like includes a unitary circular shaped plastic lid provided with a depending skirt portion. The top surface of the lid includes an inverted V-shaped bead extending concentric with and inwardly spaced from the outer circumference of the lid to provide a bead for retaining a plurality of similar lids in stacked relation, precluding them from slipping inwardly relative to each other. The top surface of the lid also includes a depressed centrally located area, which rigidifies the lid and provides a recess for labels containing printed indicia. The skirt of the lid includes a bottom, outwardly flared portion enabling the lid to be grasped and readily removed from tight fitting engagement with an ice cream carton and an upper, recessed portion to accommodate expansion of the ice cream carton without the lid popping off the carton.
